Hi Dolf.
Ya Buddy, I do assemble almost the entire figure first, before primer. The rifles are molded with the hands in this case, so there's no separation there, but I would do them separately if I could.
It really depends on the figure and how it's sculpted. My SBS', "U-Boat Watch Officer",
https://www.planetfigure.com/threads/alpines-1-16th-scale-german-u-boat-watch-officer.118351/ , there's not much gear there, but the concept is the same, the head is painted separately, but the figure is otherwise fully assembled. It can be a pain to paint around gear, etc, but sometimes they can't be separated. I personally feel the figure flows much better tonal-wise when the main body is assembled and painted. The gear, heck ya, do that separate, if you are able to, but this is not always the case.
Clear as mud, I know, but I hope that helps, Dolf.
Nap, thanks Amigo. I'll bet you guys have tube putty similar to the Testors across the pond. It was a fluke experiment for me, turns out it works quite well. The Bren gunner is in progress, but then things will slow quite a bit once the paint starts flyin. I'm a slow painter, HA!
Thanks Gents!
